Pressure Retaining Valve | V86

Pressure Retaining Valve - Overview

The V86 Pressure Retaining Valve works to keep the pressure at the valve inlet constant at all times, ensuring problem-free operation of the system as a whole. It is made for pipes of larger dimensions. The V86 pressure retaining valve serves to keep the working or system-related pressures constant, to balance out pressure pulsation and to reduce pressure peaks in chemical process systems. If the inlet pressure rises above the set value, the pressurised valve piston is lifted against the spring resistance. As a result, the valve opens and the pressure in the outlet pipe is reduced. The valve closes as soon as the inlet pressure sinks below the pre-set spring tension. For neutral and aggressive media with a small number of particles or solids. The chemical resistance depends on the selected valve material.

Pressure Retaining Valve - Features
- No auxiliary energy required
- The working pressure is set with an adjusting screw and locked with a locking nut
- Valves can also be adjusted under working pressure
- Minimal maintenance and can be installed in any position
- All parts in contact with medium made of highly resistant plastics
- Large form of the housing allows good flow values

Lug Style Butterfly Valve | 578

Lug Style Butterfly Valve - Overview

The Lug style butterfly valve has all-plastic housing which combines quality and durability. Through the use of fibreglass-reinforced polypropylene, the valve's weight is greatly reduced. This simplifies not only the installation of the valve but also saves on the storage cost. The valve can be used reliably in highly corrosive applications and is excellent for use with aggressive media. The system allows the exchange of individual system components at any time - quickly and easily, without much effort. Since the actuation torque is strongly dependent on the internal pressure, type 578 is optimally designed in this area. The maximum nominal pressure is 10 bar on both sides at 20 °C. A further benefit of this is the long life span since the valve is less exposed to wear and tear.

Lug Style Butterfly Valve - Features
- Corrosion resistant
- Stable and Reliable
- Easy maintenance
- Long life span
- Minimal operation torque
- Can be fitted with an actuator (optional)
- Lever positioning clearly marked
- Can be used with electric position indicators (optional)

The type 369 Wafer Check Valve is designed especially for large installations. It requires little maintenance and is extremely compact. The design is optimised for installations between ISO/DIN as well as ANSI/BS connections. The flap traps can be installed either horizontally or vertically. When the medium flows, it opens up the plate of the flap trap, allowing the medium to flow through. The flap closes again if the medium pressure falls below a certain threshold. The flap traps of Type 369 are intended to prevent media from flowing back within the allowable pressure and temperature range. The flap traps are available with or without a return spring made of V4A or Hastelloy. This is suitable for use in water treatment and the chemical process industry.

Wafer Check Valve - Features
- Self-closing check valve
- Horizontal or vertical installation (water column/gravity / optional spring)
- Installation between both ISO/DIN and ANSI/BS connecting elements
